Title: Improvements in and relating to the production of oxygen-containing compounds
IPC: C07C27/22
Filed: 1949-09-12
Abstract: Oxygen - containing compounds, especially aldehydes, are made from C4 and higher alkenes containing di- or poly-enes, which may be alicyclic or aliphatic, by carbonylation in the liquid phase in a first stage at elevated temperature and pressure with a mixture of CO and H2 in which the molar ratio CO : H2 is at least 2 : 3 in the presence of at least 0.3 per cent by weight of Co calculated as metal, in the form of a dissolved cobalt compound, until reaction is established as indicated by temperature rise and then continuing the reaction in a second stage using a mixed carbonylation gas of molar ratio CO : H2 of 3 : 7 to 2 : 3 and in the presence of an amount of Co which may be less than 0.3 per cent as hereinbefore defined, but is not less than 0.1 per cent.  Preferred alkenes contain from 4 to 18, especially 4 to 12, carbon atoms in the molecule.  Also preferred are C6-C8 normal mono-olefines, especially a -olefines.  Mixed olefines made by cracking higher hydrocarbons, e.g. paraffin wax, may be used.  Temperatures specified are 130-190 DEG  C., preferably 150-175 DEG  C.  Pressures specified are 200-300, e.g. 250, atmos. Preferably in the first stage of the carbonylation process the partial pressure of Co is at least 100 atmos.  Preferably soluble salts of cobalt with organic acids are used and many are specified. Aldehydes obtained may be hydrogenated to the corresponding alcohols using copper or nickel catalysts and pressures of about 250 atmos. Copper-on-zinc oxide or on-chromium are especially suitable catalysts for this stage.  In an example a C6-C8 feed is used, the first stage operates at 150-160 DEG  C. and 250 atmos. with a 40 per cent CO and 60 per cent H2 carbonylation gas and 0.3 per cent Co derived from cobalt naphthenate, and in the second stage 30 per cent CO and 70 per cent H2 is used with 0.1 per cent Co. Normal heptanol and 2-methyl hexanol are obtained from normal hexene and the corresponding alcohols from normal heptane and octene.  In the Provisional Specification the catalyst may be in suspension and there is no upper limit to the ratio of CO : H2 in the second stage.

Abstract: 1,210,992. Control of A.C. motors. TEXAS INSTRUMENTS Inc. 8 May, 1969 [7 June, 1968], No. 23565/69. Heading H2J. The starting winding of a motor is disconnected by a bi-metallic disc switch when a thermistor reaches a threshold temperature. The thermistor is connected across the main winding of the motor and the series combination of the starting winding and the switch, and has a transition temperature above which its resistance increases abruptly. In another arrangement, the thermistor is connected across the starting winding so that it remains energized by induced voltage after the supply voltage is removed from the starting winding. In a further embodiment, the starting winding 1 is energized through triac 15 when the motor is switched on. Heat regenerated in thermistor 23 is communicated to thermistor 19 whose resistance increases to de-energize the triac. If the motor fails to start, the thermistors are permitted to cool and the triac is rendered conductive for a new starting attempt.

Title: Determination of the evaporation curve for liquids by the thermogravimetric method
IPC: G01N5/04
Filed: 1957-09-25
Abstract: <PICT:0865074/III/1> <PICT:0865074/III/2> Liquid mixtures are analysed by the "evaporation" method in which the weight is continually measured on a balance, the temperature of the escaping vapour measured by a thermocouple, and the rate of loss of weight calculated.  In Fig. 2 the liquid mixture is contained in a stoppered vessel 58 in a metal dish 62 heated by an electric heater 63 situated at one side (to avoid buoyancy effects from rising hot air) and joined by a thermally-conducting member 64.  The temperature of the issuing vapour is measured by the thermojunction 66.  The metal dish can be inside the vessel instead of outside (Fig. 1, not shown).  The main heating of the vessel is achieved by placing it in a furnace 14 (Fig. 3), and the auxiliary heating mentioned above serves to keep the evaporation temperature slightly above the ambient, to prevent overheating of the vapour.  The vessel is attached to one arm of a balance 8 whose reading is detected photoelectrically or electromagnetically as in Specification 865,073 and displayed on a meter showing rate of change of weight.  As in Specification 865,073 the meter readings are recorded on photographic paper 20 in the form of TG (weight), DTG (rate of change of weight) and T (temperature) curves, together with calibration marks.  The DTA facilities are not used for the present invention.

Title: Photographic lens shutter with a braking mechanism for the control of the exposure time
Inventor: WEISE JOHANNES
IPC: G03B9/64
Filed: 1955-08-18
Abstract: 774,853. Photographic shutters. VEB ZEISS IKON DRESDEN. Aug. 18, 1955. No. 23841/55. Class 98(1) A shutter has spring-loaded blade-driving means brought to a tensioned position on the actuation of the trigger, a braking mechanism regulating the exposure time, and a control element which is influenced by the braking mechanism, wherein on continued actuation. of the trigger the sector driving means starts to run down and the control element interrupts the running- down movement of the sector driving means in a position which causes the shutter aperture to remain open during an interval of time regulated by the braking means, after which the control element releases the sector driving means to continue its running-down movement for the purpose of closing the shutter aperture. As shown, as applied to a two-blade shutter, the trigger 12 is depressed to rotate the lever 3 clockwise against the action of the spring 21 to slide inoperatively of the roofedge 25 of the blade-driving lever 7 and, by means of the pin 17, to rotate the threearmed master member 5 counterclockwise to tension the driving spring 8. The movement of the arm 28 from the lug 37 permits the control ring 2 to rotate clockwise under the action of the spring 9 until the projection 15 strikes the stop 45, the locking lug 6 moving into the path of the point 22 of the lever 3. The arm 26 of the master member 5 slides over the bevel 27 of the retarding means 29, and the lever 34 coupled to the ring 2 moves into such a position by the action of the spring 43 that the anchor 33 engages the anchor wheel 32: After tensioning, the projection 19 of the trigger leaves the edge 18 of the lever 3, which then rotates counterclockwise to engage the blade-driving lever 7 at the roof-edge 25 and turn it counterclockwise to open the shutter, and the point 22 engages the locking lug 6 to stop the control ring 2. The master member 5 follows the movement of the lever 3 but is retarded by the retarding means 29. The arm 28 finally pushes the lug 37 on the control ring 2 to rotate it and move the lug 6 from the path of the point 22, whereupon the lever 3 abruptly continues its counterclockwise movement to strike the end 39 of the bladedriving lever 7 to reverse the direction of movement of the lever 7 and close the shutter. The lever 34 is rocked by a cam 46 to disengage the anchor 33 from the anchor wheel 32. For a very short exposure time, the cam surface 35 of the speed setting means brings the pawl 10 into position to engage the lug 40 of the ring 2 so that the ring 2 cannot rotate to place the lug 6 in the path of the point 22. The lever 3 is thus not stopped during its blade-operating movement and closure of the blades follows immediate after opening. The cam surface 42 of the speed-setting means also moves the retarding means 29 so that the bevel 27 is no longer in the path of the arm 26 of the master member 5, and the blades are driven by the combined action of the springs 8 and 21.

Abstract: 156,876. Bolitho, J. B. Oct. 6, 1919. Thermionic modulating systems.-In order to modulate the oscillations produced by a threeelectrode valve with a retro-active coupling, a control circuit containing a three-electrode valve has an inductance therein coupled with an inductance in the generator circuit in such a way that the reaction between them opposes the retro-action in the generator circuit. The generating-valve has inductances 8, 10 in its plate and grid circuits respectively coupled retroactively. The control circuit contains a highvoltage supply 12, such as an alternator or a three-electrode valve, and an inductance 11 in the plate circuit 4, 6. The grids 5, 2 and filaments 6, 3 are connected and a condenser 13 enables the circuit to be tuned to the same frequency as the circuit 8, 9. The inductance 11 is coupled with the inductance 10 in the reverse direction to that of inductances 8, 10. A telephone circuit may be included in the plate circuit of the control valve instead of the voltage supply 12. When negative potential is impressed on the plate of the valve 4, 5, 6, it is inoperative and the valve 1, 2, 3 can oscillate, but when positive potential is on the plate of the valve 4, 5, 6, this valve will oscillate but the reaction of the inductance 11 on inductance 10 more or less neutralizes that of inductance 8, so that the energy produced by the valve 1, 2, 3 is correspondingly varied.
